Discussion
A cold front will move through east central florida today with a
small shower threat...

Marine conditions will deteriorate behind the front tonight...

Periodic unsettled weather conditions return Tue thru Thu with
potential lightning storms and higher rain chances...

current... 915 mhz CAPE wind profilers show deepening southwest flow
above the surface ahead of an approaching cold front. Evening
regional sounding data and water vapor imagery continue to show dry
air across the mid upper levels of the atmosphere. Conditions
continue to be precipitation free over ecfl with light variable to
calm surface winds. Temperatures mainly in the 50s with a few l60
degree readings along the space treasure coasts early this morning.

Will monitor for some shallow, patchy fog, but boundary layer winds
may be too much to overcome for formation, outside of prone and low-
lying areas.

Today-tonight... A weakening upper trough approaching the eastern
seaboard will push a weak cold front southward across east central
florida today. By sunrise, the boundary should lie across the
northern peninsula, then move into our northern zones i-4 by early
afternoon. This feature should lie around the treasure coast by
early evening, then continue to push towards southern fl and the fl
straits overnight. The flow aloft remains mainly zonal, but any
mentionable mid-level energy will remain well north of the area.

Pwat values under 1 inch will slowly recover in upwards of 1.60
inches associated with a narrow band of moisture along the front
itself. Precip chances will range from 20 to 30 percent from vero
beach-southern osceola county northward from 15z thru 00z. Overall
rainfall amounts will remain rather light. Low end precip chances
will continue mainly south from melbourne after 00z with chances
continuing to decrease southward through the evening and overnight.

Surface high pressure will build into the area from the north and
west late overnight.

Early morning winds will become southwesterly and increase to 8-13
mph while veering toward the west thru the day ahead of the front,
then the wind component will sharply veer to wnw NW behind the
boundary becoming nnw N thru the night with speeds remaining
somewhat elevated at 5-10 mph. Increasing clouds from the north to
south will occur with the approach of the boundary. Skies will
improve again from this evening-overnight, again from the north to
south across ecfl.

Temperatures will range from the m70s along north of i-4 to
u70s l80s southward toward lake okeechobee. Both cooler drier air
will filter southward down the peninsula overnight with m-u40s north
of i-4 and generally 50s elsewhere, except some l60s possible along
the treasure coast.

Mon-mon night... The area of high pressure over the southeast u.S.

Will push eastward and off of the mid atlc coast Mon night. N ne
winds will veer easterly through the day. The previous front remains
stalled across the fl straits into Mon night, but deep layer
moisture will begin to return overnight with some showery
precipitation developing over the coastal waters and potentially
along the treasure coast. Highs in the low to mid 70s. Milder lows
generally in the 60s, except u50s north of i-4.

Tuesday... An inverted trough with a weak surface low over the
northeastern gulf of mexico will support a southerly flow with
additional moisture. The weak surface low is forecast to move across
north florida during the afternoon and evening. This combined with
the enhanced moisture and impulses of shortwave energy aloft will
lead to high rain chances areawide. Rain chances taper off gradually
farther south as distance from the weak surface low increases. Will
keep a slight chance for thunderstorms.

Wednesday-Friday... Guidance generally agrees that multiple pieces of
mid upper level energy will shift down the rockies plains and carve
out the base of a larger scale trough over the gulf. Will continue
to chance pops from mid to late week as consensus suggests multiple
opportunities for precipitation, particularly on Thursday.

Saturday-Sunday... A brief, weak ridge of high pressure will build
across the region providing a dry weekend with a return to
seasonable temperatures.

Aviation Continued mainlyVFR. Stronger wind speeds above the
surface may limit fog formation this morning. SW W flow around 10
kts today ahead of a cold front will veer to NW N behind it later
today tonight. Brief MVFR shower potential along a narrow band of
moisture associated with the front. Skies becoming mclear tonight
again behind the boundary (from north to south).

Marine Today-tonight... Sw W winds ahead of an approaching cold
frontal boundary. This feature will reach the northern waters by
early afternoon, then continue to slide southward and should
approach sebastian inlet by around 7pm 00z tonight. Winds will veer
nw N behind this feature through late evening and then nne ne
overnight. Wind speeds will approach 15-20 kts over the open atlc,
north of the CAPE from mid-late afternoon and continue to spread
southward over the waters into the evening. While cautionary
statements may be necessary offshore, north of the CAPE later in the
afternoon, will go ahead and initiate an small craft advisory for
both marine legs, north of volusia-brevard county line at 7pm 00z,
then spread southward across the remainder of the waters at
10pm 03z. Winds will reach 20 kts in the advisory with frequent
higher gusts, but seas will be slower to respond. Expect seas over
the gulf stream to reach 6-7 ft over the gulf stream by daybreak mon
morning. The north wind (opposing the gulf stream) and developing
shorter period seas this evening overnight will also make for rough
small craft boating. A narrow band of light, showery precipitation
will accompany the front.

Monday... The small craft advisory continues thru Mon night as winds
continue to veer toward the east and approach 20 kts sustained with
higher gusts likely. Seas build to 5-7 feet over the gulf stream and
5-6 ft near shore.

Tuesday... Poor to hazardous boating conditions as seas of 5-6 feet
in the offshore waters will continue to build to 7-8 feet. Winds and
seas gradually diminish through the day on Tuesday, but high rain
chances along with a few thunderstorms will keep conditions less
than favorable.

Wednesday-Friday... Guidance indicates multiple weak troughs or lows
in vicinity of our waters. Some increase in winds possible on
Thursday if the low pressure becomes better organized. Expect winds
to be generally from the north to northwest with seas 3-5 feet until
Friday when seas build due to increasing winds.
